THE Family Planning Association sperm bank has broken two records by having the highest number of donors and the lowest insemination rate at the same time.
In the first seven months of this year, 109 donors visited the association; in the previous 10 years no more than 100 donors showed up per year.
Statistics also show that only 36 inseminations were made this year, compared with the second lowest record of 60 last year.
The association's executive director, Dr Margaret Kwan Shuk-wa, said the figures reflected a high failure rate in sperm tests.
''Ninety per cent of donors failed our physical examination. We found troubled semen, having low density or containing white blood cells. In some cases, we found protein in urine and some donors had high blood pressure,'' Dr Kwan said.
She believed that fewer than 10 per cent would reach a second test, which shows whether donors are infected with HIV.
